This is just a thought, but I wonder if in the past a previous owner replaced the dial scale. The code 125 chassis used a different dial than previous runs which had a different frequency calibration. Does the dial look original or was it possibly replaced?
When you did the alignment is trimmer #40 at max capacity (tight)? Are antenna 22A and mixer grid 22B trimmers also fully tight? It seems unusual that the radio receives well if the oscillator is off since it must track with the antenna and mixer tuned circuits.
